Better track management (track hiding)

+1

Using the current group function is not good enough. It can actually lead to performance issue if the group contains too many cpu intensive effects because all of the tracks in the group are forced to be processed on the same core instead of efficiently being spread across multiple cores.

Completely hiding track sets would also be an wonderful added bonus.

+1 for better track management in Live. A track list and ability to hide tracks (and call up different combinations of shown/hidden tracks via recallable views/subsets)
